ProDV® (Spheri Valve / Dome Valve)

Bulk material handling valve

The operating efficiency of all Schenck Process Systems relies upon the original and world’s best ProDV® (Spheri Valve / Dome Valve), currently installed in over 10,000 applications worldwide. Simple in design and low in maintenance, this high performance valve is used thoughout a wide range of industries.

In action, the Schenck Process ProDV® (Spheri Valve / Dome Valve) is a pressure tight compressed air operated valve, capable of returning over one million maintenance-free cycles, even in abrasive, hazardous or toxic applications. ATEX compliant – the fast-closing cut-off valve incorporates a unique inflatable sealing mechanism, this provides the pressure tight seal, against the dome surface when in the closed position.

The Schenck Process ProDV® is ATEX Compliant

Totally unrestricted full bore material flow is assured through the unique design of the ‘dome’ assembly. A mere quarter turn is sufficient to move from the fully closed to the fully open position. This action positions the dome completely clear of the material flow path.

From Fine Abrasive Powders to cohesive Materials user options extend to the choice of ‘Dome’, both in terms of raw material and any surface coatings required.

The Dome is usually produced from Cast Iron, S G Iron or Stainless Steel, but other materials and designs will be considered by application.

From Foodstuffs to High Temperature Ash a range of inflatable seals are available, depending upon the application. The choice includes a white food grade seal as well as those specially formulated for high temperatures or other hostile applications. Moving and Static Column Cut Off All Spheri Valves / Dome Valves are capable of handling fine grain materials and hard abrasive products.

Vane Actuator Models can cut through static columns of material up to 2mm particle size. They can also cut through moving columns of powders, pastes and granular products similar to coal above 2mm. Cylinder Actuator models have the added capability of being able to cut through static columns of material above 2mm.
